Googles Self-Driving Cars Could Have External Airbags

The Concept of External Airbags in Self-Driving Cars

The idea of external airbags for self-driving cars might sound futuristic, but it’s a concept that’s gaining traction as we move towards a world where autonomous vehicles are commonplace. The rationale behind this development is to enhance pedestrian safety in the event of a collision, a critical aspect of road safety that traditional safety features like crumple zones and seatbelts struggle to address.

External airbags, also known as pedestrian airbags, are designed to deploy outwards from the vehicle, creating a protective cushion between the car and any pedestrians or cyclists who might be in the path of a collision. This innovative technology promises to mitigate the severity of injuries and potentially even save lives.

How External Airbags Function

External airbags are typically housed within the vehicle’s bumper or other exterior components. They are triggered by sensors that detect an imminent collision, deploying in milliseconds before impact. The deployment mechanism involves inflating the airbag with a gas, similar to the way traditional airbags function. The difference lies in the direction of deployment, with external airbags expanding outward, away from the vehicle.

The inflated airbag acts as a cushion, absorbing the impact energy and reducing the force exerted on the pedestrian or cyclist. This significantly reduces the risk of serious injuries, such as head trauma, bone fractures, and internal bleeding.

Benefits of External Airbags Compared to Traditional Safety Features

External airbags offer several advantages over traditional safety features, making them a valuable addition to the safety arsenal of self-driving cars:

• Enhanced Pedestrian Protection: Traditional safety features, like crumple zones, are primarily designed to protect occupants within the vehicle. External airbags, on the other hand, focus specifically on mitigating injuries to pedestrians and cyclists, a critical aspect of road safety often overlooked by traditional designs.
• Improved Collision Mitigation: External airbags can significantly reduce the severity of impact in a collision, potentially preventing fatal injuries. This is achieved by absorbing impact energy and creating a buffer between the vehicle and the pedestrian.
• Increased Safety for Vulnerable Road Users: Pedestrians and cyclists are particularly vulnerable in collisions with vehicles. External airbags offer a significant safety enhancement for these road users, making self-driving cars a safer option for everyone.

Technological Challenges and Considerations

The concept of external airbags in self-driving cars presents a range of technical challenges and considerations. These challenges stem from the need to design and implement a system that can effectively protect pedestrians and cyclists in the event of an accident while also being compatible with the vehicle’s design and operating environment.

Design and Implementation Challenges

Designing and implementing external airbags poses significant technical hurdles. The system needs to be reliable, robust, and capable of deploying rapidly and accurately. The following list highlights some of the key challenges:

• Sensor Technology: Accurate and reliable sensors are essential for detecting potential collisions and triggering the airbag deployment. The system must be able to distinguish between a genuine collision and a false alarm, and it must be able to detect the presence of pedestrians or cyclists in the vehicle’s path.
• Deployment Mechanism: The airbag deployment mechanism must be fast, powerful, and safe. The system must be able to deploy the airbag in a fraction of a second, and it must do so without causing any harm to the vehicle or its occupants.
• Airbag Design: The design of the external airbag is crucial to its effectiveness. The airbag must be large enough to provide adequate protection, but it must also be lightweight and compact enough to be stored within the vehicle.
• Integration with Vehicle Design: External airbags must be integrated seamlessly into the vehicle’s design. This includes considerations for the vehicle’s aerodynamics, structural integrity, and aesthetics.

Impact on Vehicle Design and Aerodynamics

External airbags have the potential to significantly impact vehicle design and aerodynamics. The presence of a large, inflatable structure on the exterior of the vehicle could affect its airflow patterns and drag coefficient. This could lead to a decrease in fuel efficiency and an increase in noise levels.

• Noise Levels: The deployment of an external airbag could create significant noise, which could be disruptive to other road users and pedestrians.
• Vehicle Aesthetics: The integration of external airbags could affect the vehicle’s overall aesthetics. The design must be carefully considered to ensure that the airbag system is both functional and visually appealing.

Safety Considerations

The deployment of external airbags presents several safety considerations. The system must be designed to minimize the risk of injury to pedestrians, cyclists, and vehicle occupants.

• Pedestrian and Cyclist Safety: External airbags must be deployed in a way that does not cause harm to pedestrians or cyclists. The airbag must be designed to provide a soft and cushioned barrier, and it must be deployed in a way that does not impede the movement of pedestrians or cyclists.
• Vehicle Occupant Safety: The deployment of external airbags must not pose a risk to vehicle occupants. The airbag must be designed to avoid causing any injuries to occupants, and it must be deployed in a way that does not interfere with the vehicle’s safety systems.
• Environmental Considerations: The deployment of external airbags could have environmental implications. The airbags must be designed to be biodegradable or easily recyclable.

Impact on Pedestrian Safety: Googles Self Driving Cars Could Have External Airbags

External airbags, designed to deploy outward from a vehicle, have the potential to significantly improve pedestrian safety in collisions. These airbags, acting as a protective cushion, can absorb the impact of a pedestrian’s body against the vehicle, potentially mitigating severe injuries.

Effectiveness Compared to Other Safety Measures

External airbags offer a unique safety advantage compared to traditional safety measures, such as crumple zones and pedestrian detection systems.

• Crumple zones, designed to absorb energy during a collision, primarily focus on protecting the vehicle’s occupants. While they can indirectly benefit pedestrians by reducing the severity of the impact, they don’t directly cushion the pedestrian’s body.
• Pedestrian detection systems, using sensors and cameras to detect pedestrians, primarily aim to prevent collisions altogether. However, they are not always effective in preventing all collisions, especially in complex scenarios or when drivers react too slowly.
• External airbags, on the other hand, provide a direct safety barrier for pedestrians, potentially reducing the severity of injuries even in unavoidable collisions.

Scenario: Protecting Pedestrians in a Collision

Imagine a scenario where a self-driving car, traveling at a moderate speed, is unable to avoid a collision with a pedestrian crossing the street.

In this scenario, external airbags deployed from the car’s sides and hood could significantly mitigate the impact on the pedestrian. The airbags would act as a soft barrier, absorbing the pedestrian’s kinetic energy and reducing the force of impact. This could prevent or minimize injuries like head trauma, broken bones, and internal bleeding.

Ethical and Legal Implications
